IDetermining Standard Deviation and Variance from List Data

You can use functions to determine standard deviation and variance for specified list data. This calculation is performed in the RUN • MAT (or RUN) mode. You can perform calculations using data you saved to a list (List 1 to List 26) with the STAT mode List Editor or list data you input directly on the RUN • MAT (or RUN) mode screen.

Syntax	StdDev(List n [,List m])
	Variance(List n [,List m])
	List n........Sample data
	List m.......Frequency data
Example	To store the x-data below in List 1, the frequency values in List 2, and
	determine the standard deviation and variance
	x	60	70	80	90
	Frequency	3	5	4	1

1.From the Main Menu, enter the STAT mode.

2.Use the List Editor to store the above data.

3.From the Main Menu, enter the RUN • MAT (or RUN) mode.

4.Press the keys as follows.
